Term::extendedcolor provides functions for sending so called extended escape sequences to the terminal. this ought to be used with a 256-color compatible terminal.

the codes generated by this module comply to the extension of the ansi colors standard first implemented in xterm in 1999. the first 16 color indexes (0 - 15) are the regular ansi colors, while index 16 - 255 are the extendes ones. most terminal emulators support this extension.
